Mom has moderate to severe dementia, though often during the day is aware of surroundings. Where is the appropriate place her to live?

She has macular vision problems that makes it hard for her to see even the tv clearly. This coupled with some OCD's issues makes her anxious and afraid. She presents Mid mornings and up to her afternoon nap time she is like " the mother I always knew". After her nap she is quite disoriented and needs more cues and directions with ADL's and is unclear of time of day or even what day it is. I want this move to be where she feel safe as well as with peers that are at her stage of dementia. Thanks for any help you can give me.
